Conversation Orientation Moderates the Relationship between Information Sharing of Medically Assisted Reproduction and Child Adjustment

Parents who experienced infertility have increasingly used medically assisted reproduction (MAR) to add children to their families over the past few decades. These parents will need to decide if they will tell their children about being conceived using MAR. Although MAR information sharing operates within family contexts, little is known about the role of conversation orientation—one family contextual factor—in child outcomes associated with MAR information sharing in middle childhood. Derived from the Family Communication Patterns Theory, this study proposes that conversation orientation moderates the associations between MAR information sharing and children's psychosocial adjustment. This proposal was tested using a sample of 81 6- to 12-year-old MAR-conceived children from 55 families and a structured observational measure of conversation orientation. Multiple regression analyses showed that MAR information sharing interacted with conversation orientation to influence children's behavioral and attention problems but not emotional problems. In families with high conversation orientation, MAR information sharing was not significantly associated with children's behavioral and attention problems. In families with low conversation orientation, MAR information sharing was significantly associated with an increase in children's behavioral and attention problems. Results of this exploratory study demonstrate the potential significance of general communication orientation in understanding child outcomes of MAR information sharing and highlight the needed family context nuances in MAR research.     

Impulsivity,sensation seeking and reproductive behaviour: A life history perspective

Impulsivity has often been invoked as a proximate driver of different life-history strategies. However, conceptualisations of “impulsivity” are inconsistent and ambiguities exist regarding which facets of impulsivity are actually involved in the canalisation of reproductive strategies. Two variables commonly used to represent impulsivity were examined in relation to reproductive behaviour. Results demonstrated that sensation seeking was significantly related to strategy-based behaviour, but impulsivity (defined as a failure to deliberate) was only weakly correlated. The effect of impulsivity disappeared when sensation seeking was controlled. Sex differences emerged for sensation seeking but not impulsivity. We conclude that “impulsivity” is not a unitary trait and that clearer distinctions should be made between facets of this construct.     

On additivity of duration reproduction functions

In the present paper properties of theoretical response functions in the duration reproduction task (drt) are studied. If the drt response is to be interpreted as the measure of a temporal duration elapsed in the past, the reproduction function (rf) must be additively measuring. The additivity property is defined for bivariate rfs, taking into account the delay between retention and reproduction. The requirement that an rf be additively measuring leads to a system of two functional equations, which are solved by (i) linear functions of time, or (ii) functions of the form yielded by the ‘dual klepsydra model’ of duration reproduction [Wackermann, J., & Ehm, W. (2006). The klepsydra model of internal time representation and time reproduction. Journal of Theoretical Biology, 239, 482-493]. This result supports the outstanding rôle of the ‘klepsydraic reproduction function’ (krf) in models of internal representation and reproduction of temporal durations.     

La fécondation artificielle post-mortem dans le Code civil Hellénique

Medically assisted reproduction offers a technique that allows to have children of a recently deceased person. This is provided for in the Hellenic Civil Code. This article analyzes and criticizes the conditions of post-mortem assisted reproduction according to the Hellenic Civil Code.     

Observed Mother– and Father–Child Interaction Differences in Families with Medically Assisted Reproduction‐Conceived Twins and Singletons

Increased medically assisted reproduction (MAR) use to treat infertility has resulted in a growing twin birth rate. Little is known about parent–child relationships for twin relative to singleton children in middle childhood. This study fills this gap by examining parent–child relationships in 57 families with eighty 6‐ to 12‐year‐old MAR twin and singleton children using observational data (warm and supportive communication, control, and hostility). Nested ANCOVAs indicate that while mothers exhibit similar interactional behaviors toward twins and singletons, fathers have less optimum behaviors toward twins relative to singletons. Twins displayed less engaged behavior with mothers and fathers relative to singletons. Given the vitality of parent–child relationships for family and child adjustment, future studies should examine determinants and outcomes of twin–singleton relationship differences to bolster twins’ and their families’ functioning.     

A bare bones bacterial foraging optimization algorithm

Bacterial foraging optimization (BFO), based on the social foraging behaviors of bacteria, is a new intelligent optimizer. It has been widely accepted as an optimization algorithm of current interest for a variety of fields. However, compared with other optimizers, the BFO possesses a poor convergence performance over complex optimization problems. To improve the optimization capability of the BFO, in this paper a bare bones bacterial foraging optimization (BBBFO) algorithm is developed. First, a chemotactic strategy based on Gaussian distribution is incorporated into this method through making use of both the historical information of individual and the share information of group. Then the swarm diversity is introduced in the reproduction strategy to promote the exploration ability of the algorithm. The performance of BBBFO is verified on various benchmark functions, the comparative results reveal that the proposed approach is more superior to its counterparts.     

Evolutionary consumption

An overview of the field of evolutionary consumption is provided. Brief summaries of disciplines within the evolutionary behavioral sciences that preceded evolutionary psychology (EP) are first offered. This is followed by a discussion of important EP principles including the domain-specificity of the human mind, and the difference between ultimate and proximate scientific explanations. The evolutionary bases of memory, attitude formation/change, emotions, perception (our five senses), personality, and decision making are addressed next, along with specific links to consumer research. Next, I demonstrate how numerous consumer acts could be classified into one of four basal Darwinian modules: survival, reproduction (mating), kin selection, and reciprocal altruism. The paper continues with an exploration of the evolutionary roots of cultural products (e.g., song lyrics) and Darwinian happiness (along with the evolutionary etiology of maladaptive phenomena such as pathological gambling and compulsive buying). I conclude with a discussion of key epistemological benefits of Darwinizing consumer research including greater consilience, increased interdisciplinarity, and an ethos of methodological pluralism.     

Vierordt's The Experimental Study of the Time Sense (1868) and its legacy

The paper discusses the results from Vierordt's 1868 book Der Zeitsinn nach Versuchen [The Experimental Study of the Time Sense]. Illustrations of “Vierordt's Law”, the proposition that short durations are judged as longer than they really are, whereas long durations are judged as shorter, with an “indifference point” in between, are provided, mainly from reproduction experiments where Vierordt and his students or colleagues served as experimental participants. Other work from Der Zeitsinn including time discrimination and categorical timing procedures is also presented. Some subsequent research on Vierordt's Law and the “indifference point” is discussed with respect to some issues in contemporary timing theory.     

Towards an anthropology of doubt: the case of religious reproduction in Orthodox Judaism

As Israel’s Orthodox Jews struggle to live up to high fertility norms rooted in religious and Zionist ideals, an obscured model of stratified critique has emerged. Based on an ethnography of Israel’s reproductive landscape, I demonstrate how critique of high fertility standards is based on particular social and cultural capital only available to the religious elite. While well-established, knowledgeable and assertive religious members find private ways to bypass the almost unachievable levels of fertility, a veil of secrecy leaves less privileged groups, particularly ba`aley teshuva (returnees) to carry most of the fertility load. Whereas scholars of religious transformation have demonstrated how religious elites act as actors and leaders of resistance, my findings illustrate an opposite pattern. Instead of disseminating this critique publicly, religious elites engage in private strategies of secrecy and creative performances of failure that enable these individuals to diverge from norms without publicly contesting them. I argue that not only is stratified critique based on social and cultural capital, it also reproduces social inequalities. By focusing on doubt, struggles, and failures engendered in “everyday Judaism,” these findings require us to refocus our inquiry on power structures within different sub-groups of Israel’s Orthodox Jews. Further, this unique case study highlights how stratified reproduction takes new shape as social and religious convictions gain and lose their force at a particular moment in history.     

Before Reproduction: The Distortion of Generation

Jean Baudrillard has posited a theory of ‘the precession of simulacra’, arguing that it is no longer possible to tell the difference between an image and the meaning it purports to represent because technology allows the image to precede its meaning. Christa Wolf, while researching Cassandra: A Novel and Four Essays (1984), traveled to Greece and discovered the ways in which language in the rational, Western model of civilization has been distorted. Both Baudrillard and Wolf are disturbed by the ways in which sign systems can be manipulated and generated, and both demonstrate the effect this has in the political and cultural arenas. This analysis intends to show how Baudrillard’s theories play out in Wolf’s narrative, and how Wolf resolves the problems thus posed through the shock of the aesthetic experience, which forces communication while it defies representation.
